JACKSONVILLE, Fla. -- A white powdery substance sent in a letter to the Jacksonville office of Sen. Bill Nelson is cornstarch, and not dangerous.
According to a statement from Nelson's office, "authorities have determined the powder sent to Sen. Nelson's office inside a threat letter today was cornstarch, not anthrax."
The statement, which came from Nelson's office via email, confirmed Nelson was in the office today but "had left by the time the letter was opened by a staff member."
Six people on the 20th floor of the Riverplace Tower at 1301 Riverplace Blvd., were evacuated this afternoon after a white powdery substance was found.
Those in the rest of the building were unaffected, said Tom Francis, spokesman for the Jacksonville Fire and Rescue Department.
No injuries have been reported, said Francis.
